I have a rash covering almost every inch of my body. The only new food consumed was raw shiitake mushrooms-eaten in salads over several days. Small red dots and lines everywhere with large red patches on my neck, middle back, and hips. Have had the rash for five days, with new areas of dots still breaking out, mostly on my legs. Was given a prescription for prednisone for 10 days, 39 pills, but this is serious medicine, so I am toughing it out using Sarna anti-itch lotion with menthol. Most comfortable with nothing on in cool air!
